I'm not an instructor:
I think DCP had a typo and meant either the left hand corner pocket, or the right hand corner pocket, from the perspective of the shooter.
I'd shoot the shot to the left hand pocket, because that would leave 2 rail draw shape for the 3 to the 5, where the CB would draw around the 6 and 9 nicely.
If the shot in question was the game winning 9 ball, I'd shoot it in the right hand pocket, which is an easier shot, IMO.
DCP, since I try a lot of your shots on video and post them in your threads, how about you try both ways 5 times each on video, and then I will do the same?
*EDIT* I had a total brain fart, and did not even see the 1 ball on the table! And I thought the player was shooting the 2 ball now to get on the 3. Sorry, please disregard my post
